MCP4013T-202E/CH

Overview

The MCP4013T-202E/CH is a volatile, 6-bit digital potentiometer from Microchip Technology. It features 64 taps and operates within a supply voltage range of 1.8V to 5.5V for device operation, with resistor characteristics specified from 2.7V to 5.5V. The nominal resistance is 2.1 kΩ (±20%), and it utilizes a simple Up/Down serial interface. Packaged in a 6-pin SOT-23, the component supports an extended operating temperature range of –40°C to +125°C.

Feature Summary

• 6-bit resolution providing 64 discrete tap positions
• High-voltage tolerant digital inputs up to 12.5V
• Low static current consumption of 1 µA maximum
• Configurable as either a potentiometer or rheostat

Applications

• Audio volume control circuits
• Variable gain amplifier adjustment
• Voltage reference trimming
• Sensor biasing and calibration

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +125°C) and 'T' denotes tape-and-reel packaging. Confirm the '202' code corresponds to the 2.1 kΩ resistance value. Ensure the 'CH' designation matches the required environmental compliance standards for the target market.

Selection Notes

Select this model when a low-cost, single-channel digital potentiometer with high-voltage tolerant inputs is required. The volatile memory requires power restoration to reset to the mid-scale default setting. Consider the 2.1 kΩ resistance value against load requirements and bandwidth needs, noting that settling time increases with higher capacitance loads.

Part Context

This component belongs to the MCP4011/2/3/4 family of low-cost 64-step volatile digital potentiometers. The MCP4013 variant specifically offers a potentiometer configuration in a compact SOT-23 package. It shares core electrical specifications with the MCP4011, MCP4012, and MCP4014, differing primarily in pinout and terminal availability.

Replacement Considerations

Direct replacements within the same family include MCP4011T-202E/CH (SOIC/MSOP/DFN packages). Cross-family alternatives like the MCP41xxx series offer non-volatile memory but differ in interface protocols.
